New study finds vitamin D may relate to transient tachypnea in newborns

A recent study published in Hormone Research in Pediatrics has found that vitamin D status may relate to transient tachypnea of the newborn.

Transient tachypnea of the newborn (TTN) is a respiratory disorder that occurs in newborns in the first hours after birth. TTN affects about 1% of all newborns and is characterized by rapid, difficult breathing. A full recovery is usually possible in babies born with TTN, although special attention and treatment in the hospital is required.

An increasing amount of research shows that vitamin D plays a role in the respiratory system. That being said, there haven’t been many studies that have looked at vitamin D’s role in respiratory health in newborns.

Researchers out of Turkey recently conducted a novel study to determine if vitamin D is related to TTN.

They measured the vitamin D levels of 51 infants with TTN and compared them to the vitamin D levels of 59 healthy infants.

The researchers found that vitamin D levels were significantly lower in infants with TTN compared to healthy infants. They also found that vitamin D status was not related to severity of TTN.

“Our data suggests that lower [vitamin D] levels are associated with an increased risk of TTN and vitamin D may have a role in the pathogenesis of TTN,” the researchers concluded.
